3.16.2.4.3 Fault

The Fault display element shows a fault flag. The faults page of the predefined device windows makes use of this display element.

The software treats device faults in a special way. In the variable list of a device driver the fault flags appear as variables called "faults.00" .. "faults.99". The software automatically produces a variable "config.faults.XX" for each fault flag "faults.XX" the driver defines. This configuration variable controls the priority of the fault. The Fault display element now:

• Displays the state if the fault flag (OK/FAULT)
• Displays the fault text (the description for the fault flag is distributed as a message at runtime).
• While the operator holds down the left mouse button on it, the Fault element shows the priority set for this fault.
• With the right mouse button the Fault element shows a context menu to change the fault's priority.

The attributes listed below may be configured to customize a display element of this type:

• Message ID --- The message ID addresses the parameter the element shall display or edit. The message ID consists of the device name followed by a colon and the name of the parameter. XMIT-1.faults.22 for example addresses the variable faults.22 at a device named XMIT-1 . With the ' Device Driver Index ' in the appendix of this document there is a list of variable names provided for each device driver the software supports.
